New Machine Build- Home-brew with pro parts!?!

[MitzuRazing]

Hello from north of Norway
-my first build log on the Zone-a little bit nervous..

I am in the prosess of ordering linear guides and ball screw's for my new build.
Would love some input regarding the selection of guides. I have a few in mind, all fram Zapp Automation. They have a selection of 16mm fully supported rails, different unsupported rails, and precision linear rails.
My first thougt was 1,6metre of 30mm thick unsupported rail, but then i noticed the 16mm fully supported rail- would these be better than the thicker 30mm unsupp.rails? Regarding the precision linear rails, i was thinking of 20mm profile rail, these are of course the most expensive ones- are they worth the difference in price?

Ball screw; i am thinking of dual drive on the X-axis, 20mm ball screw's with 5mm pitch, 1,5metre long each.

The Y-axis, well havent really gotten this far yet, believe i have to focus on one part at the time.. ,the same really for the Z axis, but maybe a finished solution from K2cnc..

As for the frame, i have a good supplyer of big, boxed alu-profiles locally in my town, so it looks like i will by it from them.. footprint will be something like 1,8metres X 1metre.

Any of this make sense to you pro's out there, give me a wink :=)
-Thank's!!

Btw, i have Aspire v2.0 from vectric and have buildt one wood-router previously, in MDF and with drawer slides as linear guides, M12 full thread as screw.
Probotix steppermotors,drivers and power-supply. ( http://home.no/artikar/CNC.html )

As a general guideline, no matter the size, use supported rails for best results. The smaller the rail diameter, use closer spaced supports.

There is no need to be nervous. There is no failure, just momentary bumps in the learning curve. Since you already have some experience with a CNC build, it gives you a head start on build number 2.

Please continue, and "post lots of photos" so we can all learn something.

I get the support-point.. But there is a significant difference in price between the 16mm supported rail, and the 20mm precision linear guide's, is it worth paing up extra bucks for the difference? ,i will be using the router for wood mostly, but want the ability to cut som alu from time to time..
-will try to get some photos of the framework tomorrow if time allows me to do so..

I'm firmly in the camp of 'you pay for what you get'. With that in mind however, I guess it ties into what speeds and DOC your looking for, and what tolerances you want as to which to use. Don't forget pics!

I ordered the frame today, had to do it over the phone, so no pictures yet,
but I was promised that it would be finished tomorrow afternoon...quite
exited now..
The measurements inside the frame will be 160cm X 90cm, the profiles
are 10X15cm, so the footprint will be approx 180cm X 110cm.
I have this idea to use the the frame for the cooling fluid reservoir,have calculated that it will hadle about 75 theoretical litres of water etc,
dont know if this has been done before, but I am i firm believer of
trying things out.. this also will add weight to the frame, so I recon its a good idea .
Will of course need some kind of plate to lead the cooling fluid back in the frame after it has cleared the t-nut plate on top..

[MitzuRazing]

The frame, just have to bolt it together now.. I'll se if I can get it done in the weekend..
Footprint is 180cmX110cm..
Getting closer every day now..heh'
Next step is to order the guides and ballscrew for the X-axis..

[MitzuRazing]

Yez, now I've ordered all the stuff I need for the X-axis build...
1600mm Precision linar slides with 2 bloks pr side, 2X 1500mm
ballscrews, one 3Nm Nema 23 steppermotor and one cupling,
The rest will come a little by little..

Have a nice weekend all ya'cnc geeks out there

[MitzuRazing]

I am bolting the frame together these days, almost done..
A few pic's of the brackets and the frame..
Update regarding the 20mm linear slides and the ball screws,
they are soon on theire way, hoping to get
them before easter, but the time window soon closes for that to happend..

Very nice work!

That should be a nice strong as well as pretty machine.

Thanks.
I have this idea that i might fill the frame with concrete or use it to
house cooling fluid , anyone tried this before?

Well, a little bit over two weeks ago I ordered all this from http://www.slidesandballscrews.com
-The items still isn't sent from the company yet.
Am a littlebit irritated by the fact that i wont be able to continiue the
work on the router in the easter, many days free from the regular job that i
had hoped to work on my router on..
Also, the to weeks following after easter I have free from work...
so well, maybe I just have to spend some time with my family instead..

[MitzuRazing]

A little update..
Havent gotten the items yet, but they were shipped from Englang on the 9' ,
still waiting for the tracking number, but i guess it will arrive soon as the easter is over
Have made some legs from some 4X4" and 2X4", seems rigid enoug

Will paint the legs grey I believe, have primed it for now.. A few pictures is a "must have"
Also I added a picture og some simple signs i made with my MDF router
